(a)
Interpretation:
The mixture whose particle size is
Concept introduction:
The solution is defined as usually a homogenous mixture of two liquids whose particle size is less than
The colloids are the class of mixtures that have particles size much greater than the solutions. They can be clearly distinguished because of the presence of particles that constitute the dispersed phase of the colloidal systems and render them opaque. Butter milk is an example of colloids. There are various subcategories of colloids such as sol, foam, aerosol, emulsions. The particle size of colloids lies in the range of
The heterogeneous mixtures are essentially those mixtures that have non-uniform composition. The average particle size of heterogeneous mixture or suspension is more than

- A 12-oz (355-mL) Pepsi contains 38.9 mg caffeine (molar mass = 194.2 g/mol). Assume that the Pepsi, mainly water, has a density of 1.01 g/mL. For such a Pepsi, calculate: (a) its caffeine concentration in ppm; (b) its molarity of caffeine; and (c) the molality of caffeine.arrow_forwardAn aqueous solution made up of 32.47 g of iron(III) chloride in 100.0 mL of solution has a density of 1.249 g/mL at 25C. Calculate its (a) molarity. (b) molality. (c) osmotic pressure at 25C (assume i=4).
